Thekuthamanga pamwambapawiri girderbridge craneimakhala ndi chimango chachikulu chamtengo, chipangizo choyendetsa trolley, ndi trolley yokhala ndi chipangizo chonyamulira ndi kusuntha. Mtsinje waukulu wapangidwa ndi mayendedwe kuti trolley isunthe. Miyendo ikuluikulu iwiri imakhala ndi nsanja ya m'manja kunja, mbali imodzi imagwiritsidwa ntchito kusonkhanitsa ndi kukonza chipangizo choyendetsa trolley, ndipo mbali inayo imagwiritsidwa ntchito kusonkhanitsa chipangizo chogwiritsira ntchito trolley.
Kabati yowoneka bwino imayimitsidwa pansi pamtengo waukulu, ndipo cholumikizira cholumikizira cholumikizira kapena bokosi lowongolera makina amodzi limayikidwa mu cab. Makwerero am'mbali amayikidwa pakati pa kabati ndi nsanja yam'manja. Mtengo waukuluchakuthamanga pamwambapawiri girderbridge crane chikugwirizana ndi matabwa mapeto mbali zonse ndi pakati monga malo kugwirizana.
Mmodzi mwa ubwino waukulu wakuthamanga pamwambamlatho cranesndi chakuti amatha kupangidwa kuti azigwira ntchito zolemetsa kwambiri. Chifukwa chake, amakhala okulirapo kuposa ma jib okwera pamwamba, kotero sikuti amatha kukhala ndi luso lapamwamba kuposa ma crane apamtunda, komanso amatha kukhala ndi mipata yayitali pakati pa mizati ya njanji chifukwa cha kukula kwa mamembala omwe amapanga dongosolo. .
Kukwera kwa20 tonpamwamba kuthamanga mlatho cranetrolley pamwamba pa mlatho girder amaperekanso phindu ndi kaonedwe yokonza, kulola kupeza mosavuta ndi kukonza. Ngati crane yam'mwamba ya cantilever ikufunika kukonza, ndizotheka kuti crane trolley iyenera kuchotsedwa pa bridge girder kuti ifike bwino.
Komabe, kuthamanga pamwambamlatho crane ili pamwamba pa girder ya mlatho, kotero ogwira ntchito yokonza amatha kuchita zofunikira pa malo malinga ngati pali njira kapena njira zina zopezera malo.
The20 tonpamwamba kuthamanga mlatho craneangaperekenso phindu lalikulu m'madera omwe malo apamwamba ndi ochepa. Popanga makina opangira makina apamwamba, chimodzi mwazinthu zofunika kwambiri kukumbukira ndi kutalika kwa mbedza, komwe ndi kutalika kwa mbedza pamalo ake apamwamba.
